I wonder if anyone can help, my 06 reg KA has been blowing out hot air no matter what temperature the temperature dial is set to. It is a nightmare on the rare hot days we have :-)

I have used a multimeter on the plug going to the heater control valve, I got different readings depending on where the dial was set to, including a pulsing for mid-range. This prompted me to go out and get a new OEM heater control valve thinking that was the part that was faulty. I have replaced the valve and once the engine heats up I am still getting hot air no matter where the dial is.

Thanks, it is good to know I am not going mad by thinking that the panel was working by sending the varying voltages. Maybe I should take it out and replace with a genuine ford one and try and get my money back.
